Title: An improved method and means for editing combination sound and vision recordings fortelevision
IPC: G11B27/06
Filed: 1959-10-16
Abstract: 881,796. Editing magnetic tapes; television. SIEMENS & HALSKE A.G. Oct. 16, 1959 [Feb. 20, 1959; March 20, 1959; April 6, 1959], No. 35048/59. Class 40 (2). To edit a television record tape 1, an audiofrequency marker is recorded in the monitor track 15, the mark and sound tracks 15, 14 are re-recorded in alignment with the relevant picture information track 13, the tape is cut by means 74 located by a Hall-plate head 72 sensing the mark and, after splicing, the sound is re-recorded in its original staggered position with respect to the picture. An auxiliary, perforated tape 37 carries the sound transferred via 32, 33, 34, 35 and the mark via 42, 43, 44, the head 42 being adjustable for fine assessment of the cutting point. An adjustable loop 51 enables the sound to be re-recorded in accurate alignment with the picture via 50, 49, 48, the original sound being erased by a head 47. After cutting and splicing both tapes 1 and 37, the sound is restored to its original position via 32, 33, 34a, 49, 48 or by using the tape 37, additional tracks (not shown) on the tape 37 allowing for additional sound to be added. The tapes are driven in synchronism by a rotosyn generator 62 supplying the motors 28, 59 or the motor 59 may be supplied by an alternating voltage derived from a control track on the tape 1 (Fig. 4, not shown). In another embodiment (Fig. 5, not shown) the mark is recorded on a magnetic disc drivable by the tape 1 and after alignment is played back from the disc on to an exact position on the tape, obviating the adjustment 41. In a further embodiment (Figs. 6, 7, not shown) a record of the frame or half-frame of the picture passing the pictureheads when the mark registers is recorded on the edge of a disc and immediately switched to a monitor tube to give a still picture showing the picture at the proposed instant of cut. The picture may be recorded as an FM carrier as on the tape 1 (Fig. 6) or the VF signal may be recorded direct, a Hall-plate head being used to play back VF information to the monitor. Specifications 798,927, 798,928, 798,929 and 798,930 are referred to.

The heating means 49 comprises a stationary U-section cover member 52 surrounding part of the outer cylindrical member 34 and having a radially extending spiral shaped partition 58; rings 50 are provided on the outer surface of the member 34. Hot gases enter the cover member through an inlet opening 62 and leave via an outlet opening (63, Fig. 3). Air or other fluid may be introduced into the material to be treated via an inlet 80 to promote oxidation.

Title: Corrosion-resistant treatment of metal articles
Inventor: STEPHENSON NORMAN
IPC: B22F7/08
Filed: 1957-11-12
Abstract: A metal base is coated with a corrosion resistant layer containing a Ni-Si eutectic alloy containing 12% Si by weight by a process of sintering, flame spraying or impregnation.  The process is applied to a Ni base alloy containing 18 - 21% Cr, 5% Fe, 2% co, 1.8 - 2% Ti and 0.1% C which is degassed at 900 DEG C. in vacuo, cleaned and then coated either with a mixture of Ni and Si powders or the prealloyed powder as a suspension in xylene and finally sintered in vacuo at 1150 DEG C.  The coating may also be applied by flame spraying and sintering in an inert atmosphere or a nickel coating can be applied which is then impregnated with silicon.  If the base metal contains chromium the coating should be free of chromium and if necessary the surface of the base metal may be depleted of chromium prior to the coating operation by heating it in air and removing the oxide or a layer of nickel may be applied before the coating of the Ni - Si eutectic alloy.  When coating chromium free bases the Ni - Si alloy may also contain chromium. The coated article is isothermally heat treated at 900 - 1000 DEG C. and then aged at 700 DEG C.  According to the Provisional Specification the Ni - Si coating alloy may also contain Be and/or Mg in addition to Cr.

Title: Improvements in and relating to overheated axle box detectors
IPC: B61L1/20
Filed: 1958-11-04
Abstract: 860,524. Detecting radiated heat. SERVO CORPORATION OF AMERICA. Nov. 4, 1958 [Nov. 8, 1957], No. 35438/58. Class 40 (3). [Also in Group XXX] In a system for detecting overheated axle boxes on railway vehicles, two heat detecting units, positioned on opposite sides of a railway track, are energized by heat from opposite axle boxes and an alarm and counter are operated when the difference between the received signals exceeds a predetermined value. The heat detector units 10 and 11, Fig. 3, each comprises two heat sensitive elements 14 and 15, e.g. thermistor flakes, which are mounted in a housing 20 and an optical system, including aperture 23, shutter 24 and lens 19, via which the element 14 is energized by heat received from a direction forming an angle α with the base of the housing. Element 15, which is shielded from heat entering the aperture, is connected in a bridge circuit with element 14 and acts to compensate for changes in ambient temperature. The units 10 and 11 are positioned on opposite sides of a track, Fig. 2 (10 only shown) and act in cooperation with electromagnetic wheel trips A, B and C, each of which produces an output pulse when a wheel flange passes through its magnetic air gap. Trips A and B are positioned apart at a distance equal to the wheel base of the vehicle being checked and trips B and C are positioned such that an axle box moves through the receive beam of the heat detector when its associated wheel moves from B to C. In operation, the moving vehicle produces a signal in trip A which energizes solenoids 25 via the storage circuit 30 to withdraw the shutters 24 protecting the elements 14 in the detector units 10 and 11, if the vehicle has the correct size of wheel base coincident signals are produced from the trips A and B which via a coincidence circuit 31 prepare a gate 26 for operation, additionally the gate is switched to its " on " position by the signal from trip B. The axle boxes, e.g. 22, Fig. 2, are then scanned by their respective detecting units and the signal produced in each unit is amplified and passed via the gate to the integrating circuits 40, 41 and 42, 43. The pulse from trip C switches off the gate and additionally operates relay 52 to discharge the integrating condensers 41 and 43 through the potentiometer 48. Each of the thyratron valves 55 and 56 is associated with one side of the track and is connected to a stepping relay which brings a new alarm and counter into operation each time the valve fires. The valves are normally held at cut-off and the potentiometer 48 is connected so that neither valve fires when the response from the detectors is equal, if, however, a difference exists, exceeding a predetermined value, one or other valve fires whereby an alarm is operated and the associated counter counts the number of pulses produced by the wheel trip C after the detection of the hot bearing. This count indicates the wheel position from the end of the train.

Alternatively the compounds of Formula I may be prepared by reacting a compound of formula <FORM:1026155/C4-C5/4> in which Hal is halogen, X is as above with piperidine preferably in a solvent, e.g. aliphatic alcohols, amides as above, glycols acetone or excess of piperidine.  The compounds of Formula VII are obtained by coupling a compound of formula <FORM:1026155/C4-C5/5> with a diazo compound of Formula III above, preferably in the presence of an aliphatic alcohol, cyclic ether or carboxylic acid. The compounds of the invention may be converted to acid addition salts by normal methods, many acids being specified.ALSO:1-(3-[(5,6,7,8-tetrahydro-1-naphthyl)amino] propyl) piperidine of formula <FORM:1026155/C2/1> is prepared by the reaction of 5,6,7,8-tetrahydro-1 -naphthylamine or alkali metal salt thereof with a compound of formula <FORM:1026155/C2/2> in which Hal is a halogen atom in a solvent. Alternatively the compound of formula II may be prepared from a compound of formula <FORM:1026155/C2/3> in which Hal is a halogen atom and piperidine, preferably in a solvent or in excess of piperidine at temperatures of 50-150 DEG  C. In Example 1, N-g -chloropropylpiperidine hydrochloride is converted to the free base by dissolving in water and adding ammonium hydroxide, extraction with xylene, working until nearly neutral, saturated with sodium chloride and dried over calcium sulphate.  This xylene solution is reacted with the sodium salt of 5,6,7,8-tetrahydro-1-naphthylamine under reflux, cooled to 50 DEG  C. and diluted.  The aqueous layer is evaporated and the organic layer worked with water, dried and concentrated under reduced pressure. The product is obtained as a yellow oil, B.P. 159-160 DEG  C., by distilling under reduced pressure, and solidifies in standing.
